To understand how cells function, scientists study how their different components—from single molecules to multiple organelles—work together. Using traditional structural biology techniques, they can look at individual molecules, zooming in to individual atoms. In most cases, however, this approach provides only static snapshots of molecules. To infer how molecular structures behave in their cellular environment, scientists instead use cryo-electron tomography. In contrast with other structural approaches, however, this technique does not allow them to observe the atomic details.
